    I've tried this before and failed, 2nd attempt tomorrow.

    Can i shoot my pano with 3 (canon) brackets per shot, merge each exposure into a complete pano then after all that merge the 3 panoramic shots with different exposures to a HDR panorama.

    If you haven't got a clue what i'm talking about ,,, its ok i've no idea either ;P

    The last time i ran into issues with alignment.

    at the time i was using PS CS6. now i have PS CC.

    Thanks.

    Martin.

    you'd be depending on the algorithm which does the merging to result in an identical stitch each time, which may not be as straightforward as you wanted.

    Do the HDR processing first then merge the resulting files into the pano. Be sure to replicate the same tone mapping onto all the HDR sets or else you'll end up with differences in colours and/or brightness.

    Try to avoid moving objects in the scene as ghosting can be a real pain in the ass.
    One method of dealing with ghosting is to make a second pano image using a single (matching) exposure from each of the sets of HDR's and then blending that new pano into your main pano to eliminate ghosts.

    I'm older than Minecraft goats.

    I would have thought it would be best to make the 3 panoramas first then make the HDR to avoid any differences in the way the HDR is applied?

    I've never really had any issues with the way Photoshop merges pictures. You might want to make sure you're not compressing the images, raw comes off the camera in 16bit (I think) but usually gets compressed to 8bit as far as I can remember.

    You wouldn't be using raw files for the tonemapping part then though?

    I haven't made one of them in a long time, but when I did I believed it went like this;

    Camera on fully manual obviously, fire off your 3 exposures in each position as fast as possible (leaving maybe a 30% overlap), make your 3 HDR's in Photomatix (or whatever) using same settings, merge the 3 to panorama (via LR in my case) in PS, back to LR for alignment, cropping and other adjustments.

    That what I used to do IIRC and almost always got "even" results with no obvious joins in the 3 shots.

    you could also try making an ordinary pano & then using something like nik colour effects to bring out details, sharpen & adjust colours?
    sounds like a headache otherwise :p
